Turn any text into natural speech, completely offline on your device. No internet required, no limits, no subscriptions.
Just listen to that long wall of text that you really need to read or save it for later, with the voice you want.

What is Koro about:
- Unlimited speech synthesis: turn text of any length into spoken language, whenever you need. Simulate interesting podcasts or relaxing audiobook.
- Privacy focused: everything happens right on your device. No cloud services, no data usage, no restrictions.
- Mix and match voices: choose from built-in voices or blend them together to create your own unique sound. Make it sound just right for you.
- Text import: drop in text files or PDFs and Koro will read them out loud. Great for articles, documents, or anything you want to listen to.
- Share your audio: save speeches as audio files and share them anywhere. Listen back anytime, even without the app.
- Advanced Customization: if some words don’t sound right, add their pronunciation at phoneme level for a perfect speech.
